Only one man knows in the entire world. 1. Where did we come from? 2. What is gravity? 3. What is matter? 4. What is dark matter? 5. What is dark energy? 6. What is aether? 7. What is light? After reading his book and finding out the true secrets of the universe, many are forced to wonder if this is, indeed, the greatest discovery of our time. It is a fact that sound waves (mechanical waves) require a material or medium for its propagation such as gas, solids, and liquids. The theory is th...

This book explores the Micro-World of subatomic particles and forces, including the recently discovered Higgs boson.The pursuit of nature’s smallest parts is one of mankind’s oldest quests, beginning at least 26 centuries ago. But, just in our lifetimes it seems we’ve finally “hit bottom.” Each step deeper into the Micro-World has revealed surprises, and expanded our understanding of nature on all size scales. At the bottom, we see a remarkable unity — nature is the same everywhere...

What is quantum mechanics? Learn from the experts in the ALL-NEW LADYBIRD EXPERT SERIESA clear, simple and entertaining introduction to the weird, mind-bending world of the very, very small.Written by physicist and broadcaster Professor Jim Al-Khalili, Quantum Mechanics explores all the key players, breakthroughs, controversies and unanswered questions of the quantum world.You'll discover:- H...

This book continues our exploration of the most profound theory of science, Einstein’s General Theory of Relativity. We examine more carefully the properties of spacetime, the unity of space and time. We explore the major features of curvature, how to measure it, and how to reduce its complexity to finding distances between nearby points. We find a simple expression, 2M/r, which proves remarkably helpful as we explore the Schwarzchild metric, black holes, time d...

Most avid sky gazers wait until nightfall to catch a glimpse of the stars that are scattered across the heavens. The fact of the matter is that one needs only to feel the Sun’s rays in order to experience the presence of a star. The Sun is an ordinary star, a ball of hot gas much like millions of others in the universe, but as the center of the solar system, it is critical to the survival of all life forms on Earth. This comprehensive volume examines the nature of the Sun and details the p...

This book continues our exploration of stars. Here we discuss the spectacular ways in which stars die, creating supernovae that are some of the most violent events in our universe. We also explore the exotic remnants of these explosions: white dwarfs, neutron stars, and particularly, black holes. We examine how black holes can grow as massive as small galaxies, and how they can evaporate through Hawking radiation. We talk about what stars are, how they form, the life & death ...

This book is the third stage of our exploration of Quantum Mechanics in the Everyone’s Guide Series. Here, we explore the heart of Quantum Mechanics: wavefunctions, the Schrödinger wave equation, superposition, and the virtual particles that spring forth thanks to the Uncertainty Principle.  We will see how these remarkable concepts apply to real particles in real high-energy physics experiments. Readers will benefit from a prior reading of Quantum Mechanics 1: Particle...

As the foundation for other natural sciences, physics helps us interpret both our most basic and complex observations of the natural world. Physics encompasses such topics as mechanics, relativity, thermodynamics, and electricity, among others, all of which elucidate the nature of matter, its motion, and its relationship to force and energy. This engaging volume surveys some of the major branches of physics, the laws, and theories significant to each. Also chronicled are some of the histor...

One of the best ways to succeed in Chemistry is to practice taking real test questions.
